[0023] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.
[0024] An embodiment of the present invention provides a tailgate for a vehicle. Figures 1 to 3 As shown, the tailgate includes a tailgate outer panel 1. The tailgate outer panel 1 is the basis of the tailgate, and serves as a skeleton and basic support. At the edge of the first end of the tailgate outer panel 1 (coinciding with the end close to the top cover of the vehicle after the tailgate is installed), there is an upper stop point 11 for the tailgate hole. The position of the upper stop point 11 of the tailgate hole is consistent with the Y0 position of the flange of the sealing strip on the top of the vehicle body after the tailgate is installed to the vehicle body and the tailgate is opened. The upper stop point 11 of the tailgate hole is constructed so that the X-direction distance from the calibration point is greater than or equal to 700 mm. Among them, the calibration point is the rearmost end point of the bumper of the vehicle body where the tailgate is installed. In other words, Figure 4As shown, by limiting the size of the tailgate outer panel 1, the tailgate and the top cover are adjusted toward the front of the vehicle, resulting in a larger size of the top area of the tailgate. After opening the tailgate, the rear end of the vehicle has a large operating space, which effectively avoids the problem of customers hitting their heads. In addition, the setting is simple and easy to implement. It can be understood that due to the limited size of the vehicle body, preferably, the X-direction distance between the upper dead point 11 of the tailgate hole and the calibration point is less than or equal to 750 mm. This setting takes into account the height of adults and can ensure that the problem of most customers hitting their heads is avoided. At the same time, the setting also takes into account the vehicle's own X-direction size to avoid or reduce the impact on the vehicle's top cover and the components set on the top cover.
[0025] In one embodiment, a tailgate glass frame opening 12 is provided on the tailgate outer panel 1 for mounting the tailgate glass. A tailgate inner panel 2 is provided on the inner side of the tailgate outer panel 1 to enhance the strength of the tailgate and facilitate the installation of interior decoration. The tailgate inner panel 2 has a substantially "mouth" structure and is located at the periphery of the tailgate glass frame opening 12.
[0026] Specifically, the tailgate inner panel 2 includes a first tailgate inner panel 21, a second tailgate inner panel 22 and a third tailgate inner panel 23. The first tailgate inner panel 21 is arranged outside the first end of the tailgate glass frame opening 12 and extends transversely (consistent with the left and right direction of the vehicle). The second tailgate inner panel 22 is arranged outside the second end of the tailgate glass frame opening 12 (consistent with the end away from the top cover of the vehicle and close to the bottom plate of the vehicle after the tailgate is installed) and also extends transversely. The third tailgate inner panel 23 is arranged between the first tailgate inner panel 21 and the second tailgate inner panel 22, and is respectively located outside the two sides of the tailgate glass frame opening 12. The tailgate inner panel 2 is a sheet member formed by integral stamping. Among them, the first end of the first tailgate inner panel 21 is connected to the first end of the tailgate outer panel 1. The second end of the first tailgate inner panel 21 is connected to the tailgate outer panel 1 at a certain distance from the first end of the tailgate glass frame opening 12. Preferably, the distance between the second end of the first tailgate inner panel 21 and the first end of the tailgate glass frame opening 12 is 280-300 mm, for example, 290 mm. In addition, the first tailgate inner panel 21 and the tailgate outer panel 1 form a first cavity 24. It can be seen that the first tailgate inner panel 21 is not connected to the position near the first end of the tailgate glass frame opening 12. By setting the tailgate inner panel 2, especially by forming the first cavity 24, the structural strength and layout mode of the tailgate can be improved, and the NVH performance in the vehicle can be improved. In addition, the first tailgate inner panel 21 of the tailgate inner panel 2 does not extend to the position near the first end of the tailgate glass frame opening 12, which can relatively reduce the size of the tailgate inner panel 2, optimize the structural size of the tailgate inner panel 2, effectively reduce the stamping difficulty of the tailgate inner panel, and reduce the weight of the tailgate itself.
[0027] Further preferably, at the first cavity 24, the distance between the first tailgate inner plate 21 and the tailgate outer plate 1 in the Z direction is not greater than 55 mm. It should be explained that the distance in the Z direction refers to the Z-direction distance between the line extending parallel to the Z direction of the vehicle and the two intersections of the first tailgate inner plate 21 and the tailgate outer plate 1 when the tailgate is installed and covered. Moreover, in the direction from the first end to the second end, at least one-third of the first cavity 24, the distance between the first tailgate inner plate 21 and the tailgate outer plate 1 in the Z direction is greater than or equal to 45 mm. That is, the first tailgate inner plate 21 is connected to the tailgate outer plate 1 at the first end section and the second end section, and the middle section protrudes in the direction away from the tailgate outer plate 1, and is itself constructed as a bending part. This setting defines the specific structure of the first cavity 24, and then defines the shape of the first tailgate inner plate 21. This setting not only ensures the NVH performance and strength of the tailgate, but also effectively saves space and facilitates the installation of the interior panel.
[0028] In one embodiment, a reinforcing plate 3 is provided on the inner side of the tailgate outer panel 1. The first end of the reinforcing plate 3 is arranged at intervals with the second end of the first tailgate inner panel 21 and is connected to the tailgate outer panel 1. The second end of the reinforcing plate 3 extends to the first end of the tailgate glass frame opening 12 and is connected to the tailgate outer panel 1. In addition, the reinforcing plate 3 and the tailgate outer panel 1 form a second cavity 31. In other words, the reinforcing plate 3 is provided on the tailgate outer panel 1 mainly to play a reinforcing role, ensure the structural rigidity of the tailgate, and improve the overall strength. The reinforcing plate 3 and the tailgate inner panel 2 together ensure the overall rigidity and strength of the tailgate, as well as the NVH level of the entire vehicle.
[0029] Preferably, the distance between the first end of the reinforcing plate 3 and the first end of the tailgate glass frame opening 12 is 160-180 mm, for example, 170 mm. In addition, at the second cavity 31, the distance between the reinforcing plate 3 and the tailgate outer panel 1 in the Z direction is not greater than 45 mm. It should be explained that the distance in the Z direction refers to the Z-direction distance between the two intersections of the line extending parallel to the Z direction of the vehicle and the reinforcing plate 3 and the tailgate outer panel 1 when the tailgate is installed and covered. And, in the direction from the first end to the second end, at least half of the second cavity 31, the distance between the reinforcing plate 3 and the tailgate outer panel 1 in the Z direction is greater than or equal to 35 mm. That is to say, the reinforcing plate 3 itself is a bent plate, and the first end section and the second end section of the reinforcing plate 3 are both connected to the tailgate outer panel 1, and the middle section protrudes in the direction away from the tailgate outer panel 1. The above defines the structure of the reinforcing plate 3 itself, as well as the installation position, etc., to ensure that the reinforcing plate 3 plays a good auxiliary reinforcement role, thereby ensuring the overall strength and rigidity of the tailgate, as well as the NVH level of the vehicle.
[0030] A stamped reinforcement rib 13 is provided on the tailgate outer panel 1 between the first tailgate inner panel 21 and the reinforcement plate 3. It can be understood that the stamped reinforcement rib 13 is a reinforcement rib formed on the tailgate outer panel 1 by stamping. For example, the stamped reinforcement rib 13 is a groove-shaped structure protruding inward from the tailgate outer panel 1. A plurality of stamped reinforcement ribs 13 are provided on the tailgate outer panel 1, and these stamped reinforcement ribs 13 are distributed in intervals in the transverse direction (consistent with the Y direction of the vehicle) of the tailgate outer panel 1. By providing the stamped reinforcement rib 13, the strength and rigidity of the tailgate outer panel 1 can be increased, which helps to reduce the weight of the tailgate as a whole.
[0031] The first end of the reinforcing plate 3 and the second end of the first tailgate inner plate 21 are both provided with flanges 32. The flanges 32 can be overlapped on the stamped reinforcing ribs 13. The flanges 32 are connected to the stamped reinforcing ribs 13 by welding. This arrangement can effectively improve the rigidity of the tailgate outer panel 1, thereby improving the rigidity of the tailgate as a whole, as well as the NVH performance.
[0032] In the present application, by increasing the size of the top of the tailgate outer panel 1, the seam between the tailgate and the vehicle roof is moved forward to avoid the problem of bumping the customer's head. Since the size of the tailgate outer panel 1 is increased relative to the prior art, its strength and rigidity, as well as the local mode, need to be adjusted accordingly, otherwise the NVH performance in the vehicle will deteriorate. Furthermore, by providing the first tailgate inner panel 21 and the reinforcing plate 3 on the first end side of the tailgate glass frame opening 12 of the tailgate outer panel 1, the strength and rigidity of the tailgate are improved, the NVH performance is met, and the self-weight can be effectively reduced to meet the lightweight requirements. At the same time, the first tailgate inner panel 21 and the reinforcing plate 3 respectively form a cavity (a first cavity 24 and a second cavity 31) with the tailgate outer panel 1. This structural form can avoid the problem of the cavity being too large and difficult to support, and can also meet the local mode performance. In addition, other structures, for example, the second tailgate inner panel 22 and the third tailgate inner panel 23 can be adaptively adjusted, and the connection method with the tailgate outer panel 1 can also refer to the connection method in the prior art.
[0033] The present application also relates to a vehicle. The vehicle includes the above-mentioned tailgate for the vehicle. The vehicle adopts the tailgate of the present application, which is adjusted relative to the front end of the vehicle with respect to the split of the top cover. After the customer needs to open the tailgate, there is a large operating space behind the vehicle, which effectively avoids the problem of the customer hitting his head and improves the customer experience.
[0034] In addition, in the present application, the X direction is consistent with the front-to-back direction of the vehicle, the Y direction is consistent with the left-to-right direction of the vehicle, and the Z direction is consistent with the up-and-down direction of the vehicle. In addition, the directional terms "lateral", "front", "left", "right", "rear", etc. are all based on the vehicle's own direction.
[0035] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other modifications can be made based on the principles of the present invention, which should also be considered as the protection scope of the present invention.
